boost::signals build and C++Builder 6 Pro in 1.29.0

I have built the boost::signals library with C++Builder 6 Pro Update 4 and am running into problems: a) We tend to use double word alignment, not quad word (which is the default in C++Builder). It appears that the libraries are built with quad word, but the headers don't enforce this, so when I change the options to double word (in our project) and try to construct a signal with boost::signal0<void> s; I get an access violation when constructing a signal (from line 266 of shared_count.hpp) The call stack is 00417F3F __internal_malloc 00417DD8 __internal_malloc 00417539 ___org_malloc 00416EA2 ___org_new 004076E1 boost::detail::shared_count::shared_count(this=:0012FBB4, p=:007F3928, d={ }, =:007F3928) 004063E3 boost::shared_ptrboost::signals::detail::signal_base_impl::shared_ptrboost::signals::detail::signal_base_impl(this=:0012FBB0, p=:007F3928) 0040546D boost::shared_ptrboost::signals::detail::signal_base_impl::resetboost::signals::detail::signal_base_impl(this=:0012FF70, p=:007F3928) 00403F51 boost::signals::detail::signal_base::signal_base(this=:0012FF70, comp=:0012FC24) 0040232E boost::signal0boost::function_base >

b) If I do use quad word alignment, then the object constructs correctly, but when I connect a method to it with void VoidFunc(void) { } int main(int argc, char* argv[]) { boost::signal0<void> s; s.connect(&VoidFunc); } the program hangs. Turning on CodeGuard shows a similar problem to that above. The object was allocated with a size of 12 bytes, but code is trying to access byte 16 in the object (I guess this is a similar alignment problem). The callstack is 0041E44E boost::counted_base::dispose(this=:00C04360) 00427203 boost::signals::detail::signal_base_impl::connect_slot 00404741 boost::signal0boost::function_base >

::connect(this=:0012FF60, in_slot=:0012FDA8) 004026C5 main(argc=1, argv=:00C021E4) 00433802 __startup

It says the this pointer block is only 12 bytes long, but the code is trying to access byte 16. Do (or should) all the bost headers force alignment before all structures/classes and then restore the alignment afterwards? Currently, I have to link directly with the signals source code to get use the library. Has anything to do with this been changed in the builds of 1.30.0? Thanks Russell
